ANTIRATTLER 'THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 661,149, dated November 6, 1900.

Application filed July 23, 1900. Serial No. 24,601- (No model-l To all whom it may concern.-

Be it known that I, FRANK W. MALLERY, a citizen of the United States, residing at Overton P. 0.. in the county of Wayne and State of Ohio, have invented a new and useful Antirattler ThilI-Coupling, of which the following is a specification.

My invention relates to thill-couplings for vehicles, and particularly to the class known as antirattler, intended to prevent rattling at the junction of the shaft and axle.

It consists of the novel devices and com bination of parts hereinafter fully set forth and described, and is illustrated by the accompanying drawings, in which similar figures of reference indicate like parts.

Referring to the drawings, Figure 1 is a side view of my antirattler thill-coupling. Fig. 2 is a view of one member of same, which for convenience I call the hook, detached. Fig. 3 is a view of one of my tail-irons for the shafts of a vehicle,detached. Fig. 4 is a view of the wedge-block, such as I use, detached.

In the drawings, 1 is the hook of my improved coupler, and 2 is the shank, whereby it is secured to the axle 11, by means of clip 12, in the usual way. This hook is turned upwardly and rearwardly, so that its terminus stands opposite a corresponding raised portion adjoining the shank and is provided with a furrow along its inner surface 10 and connects with a vertical furrow 9 along the inner surface of said raised portion. Itis also provided with a spring 5, made, preferably, of spring-wire and secured to the shank 2. The outer ends of the spring on both sides of the hook-opening are hinged to a saddle 6,1nade of like wire. The connection and arrangementof the spring and saddle on both sides are made alike. The tail-irons of the shafts, Fig. 3, are bifurcated, and at the outer ends of the extensions 3 3 is set a circular cross-bar 8, made pulley-shaped to enter the grooves 9 10 of the hookopening and to rest within the same, as shown in Fig. 1. A wedge-block t, Fig. 4, is constructed to enter the opening of the hook vertically, It is provided with flanges 9 10, and one side cut away to rest over and upon the upper rear portion of the cross-bar 8. The flanges enter the corresponding grooves 9 10 of the hook. A groove across its top receives the saddle of the spring 6, wherebyit is securelyheld in position against the pulley-shaped cross-bar, and thereby acts as a wedge to tighten the coacting parts of the coupling, secnresthe tail-irons of the shafts, accommodates itself automatically to wear of the joint, and prevents rattling. By moving the saddle of the spring backward, as shown at 6, the wedge block may be removed and the shafts detached from the hook'at pleasure.

I do not limit myself to the particular shape of the several parts as shown, nor to the particular manner of attaching the spring to the shank of the hook, and the same may be modified to suit different kinds of vehicles.

Having thus fully described my invention what I claim isblock having flanges to enter the opening of the hook vertically along the opposite grooves thereof, and a spring-clip attached to the shank of the hook to removably secure the said block in position bya constant pressure, substantially as set forth and for the purpose specified.
